The video card doesn't make any difference as far as speed goes, what matters is how fast your cpu(s) are. You do need a decent video card to run Dolphin, but you won't get any speed gain from it as of yet. I did post a feature request that Dolphin should actually use our video cards to gain speed, but who knows if it will happen.
